An analytical method for the determination of nitenpyram residue in cabbage and soil using gas chromatography was established. The nitenpyram residue was extracted from cabbage and soil with acetone-water (4 : 1, v/v), cleaned up by a Florisil column, and then detected by gas chromatography-electron capture detection (GC-ECD). At the spiked level range from 0.02 to 2.00 mg/kg, the average recoveries of nitenpyram were 88.73%-94.3% and 90.82%-96.27% with the relative standard deviations (RSDs) of 3.09%-7.39% and 2.01%-4.92% in cabbage and soil, respectively. The limit of detection of nitenpyram was 0.02 mg/kg. The method is fast, sensitive, simple, reproducible and practical for the determination of nitenpyram residue in environmental systems.
建立了一种用气相色谱法测定甘蓝和土壤中烯啶虫胺残留量的分析方法。用丙酮 - 水（4∶1，v/v）从甘蓝和土壤中提取烯啶虫胺残留，经弗罗里硅土柱净化，然后用气相色谱 - 电子捕获检测法（GC - ECD）进行检测。在0.02～2.00 mg/kg的加标水平范围内，烯啶虫胺在甘蓝和土壤中的平均回收率分别为88.73% - 94.3%和90.82% - 96.27%，相对标准偏差（RSDs）分别为3.09% - 7.39%和2.01% - 4.92%。烯啶虫胺的检测限为0.02 mg/kg。该方法快速、灵敏、简便、重现性好，适用于环境体系中烯啶虫胺残留量的测定。
